中文摘要:
      目的:建立用便携式气相色谱快速检测降香及相关成药的方法。方法:采用降香特征峰的保留指数对样品进行鉴别。采用DB-5毛细管柱(1m×0.25μm×0.35mm),声表面波检测器(SAW),检测器温度60℃,载气为氦气(99.999%),流速3.0 mL.min-1,阀温165℃,进样口温度200℃,预浓缩管温度250℃,柱初始温度40℃,以10℃.s-1速率升温至200℃,进样时间10s。结果:降香主要特征峰能较好分离,分析时间在1min内。经验证,方法具有较强的专属性、耐用性,能准确鉴别降香及其相关成药。结论:便携式气相色谱仪操作简便、分析快速、灵敏,可用于降香及相关成药的现场快速筛查。
英文摘要:
      Objective:To develop a method of rapid detection for Dalbergiae Odoriferae Lignum and related Chinese traditional medicine by portable gas chromatography. Methods:Retention index of characteristic peaks in Dalbergiae Odoriferae Lignum was used to analyse sample. DB-5Scapillary column(1m×0.25μm×0.35mm) was used,surface acoustic wave detectorSwas used with temperature of 60℃,Helium gas was used as the carrier gas with flow rate of 3.0 mL.min-1,the valve temperature was 165℃, theSsample inletStemperature was 200℃,the concentrated tube temperature was 250℃,the initial temperature of column was 40 ℃,then increased to 200℃ at a rate of 10℃.s-1,the injection time was 10s.Results:The main characteristic peaks of Dalbergiae Odoriferae Lignum were well separated in 1 min.,the method was specific,durable and accurate to identify Dalbergiae Odoriferae Lignum and related Chinese traditional medicine.Conclusion:The portable gas chromatography was simple,rapid and sensitive,it can be used for rapid detection in Dalbergiae Odoriferae Lignum and related Chinese traditional medicine.
